WheelGestures

🚧 Disclaimer

This project is a fork of https://github.com/xiel/wheel-gestures. It solely exists to fix some problems with type imports. The original package seems to be abandoned, thus the fork and republish.

Installation

Install @maas/wheel-gestures using your package manager:

pnpm install @maas/wheel-gestures # OR npm install @maas/wheel-gestures

Usage

Import and create an instance of WheelGestures and then add the element you want to observe.

import { WheelGestures } from '@maas/wheel-gestures'

// create an instance per element
const wheelGestures = WheelGestures()

// find and observe the element the user can interact with
const element = window.document.querySelector('.slider')
wheelGestures.observe(element)

// add your event callback
wheelGestures.on('wheel', (wheelEventState) => {
  //...
})

There are options to customize the behaviour.

WheelEventState

This is the TypeScript type of the WheelEventState object provided. Even if you do not use TypeScript, this might be helpful to see how the data is provided:

export type VectorXYZ = [number, number, number]

export interface WheelEventState {
  isStart: boolean
  isMomentum: boolean
  isEnding: boolean
  isMomentumCancel: boolean
  axisDelta: VectorXYZ
  axisVelocity: VectorXYZ
  axisMovement: VectorXYZ
  axisMovementProjection: VectorXYZ
  event: WheelEvent | WheelEventData
  previous?: WheelEventState
}
